.1 ZZZGIFECATION forming part of Letters Patent No. 340,461, dated April20, 1886.

Application filed January 7, 1885. Serial No. 152.183. (No model.)

f all whom it nwq concern.-

Be it known that we, HILBORNE L. ROOSE- VELT, a citizen of the UnitedStates, residing in the city of New York. State of New York, and OrmnLEsS. HAsKELL, a citizen of the United States, residing in the city ofPhiladelphia, State of Pennsylvania, have jointly invented certainImprovements in Cabinet PipeOrgans, of which the following is aspecitication.

The object ofour invention is the prod notion of a compact and portablepipeorgan of large power and great variety of tone.

Our improvements comprehend a novelconstructionandarrangementofthekeyaud drawstop act iou,a novel blowi ugapparatus,in which the feeders are directly applied to and so as to forma part of the bottom of the wind-chest, and a novel arrangement andapplication of a wiml-reservoir, the said improvements being allsubstantially of a character hereinafter set forth.

An organ embodying our invention is rep resented in the accompanyingdrawings, and described in this specification, the particularsubject-matter claimed as novel being hereinafter definitely specified.

In the drawings, Figure l is a vertical side sectional elevation of anorgan conveniently embodying our improvements and at rest, section beingsupposed either in the plane of the dotted line n2 in Fig. 2, and sightbeing taken from the left-hand side of said figure, or else in theplanes of the dotted lines 20 win Fig. 3, and sightbeing taken from therighthand side of said figure. Fig. 2 is a rear elevation of the same,the back panels of the case being removed. Fig. 3 is a horizontalsectional plan of the same, section being supposed either in the planeof the dotted line y 3 of Fig. 2 or in that of the line z z of Fig. 1.Figs. 4. and 5 are respectively a side elevation and a top plan view ofone of the draw-stops and its draw-stop lever. Figs. (5, 7, 8, and 9 areside sectional elevational fragmentary detailed views of parts of thekey and draw-stop actions designed in various phases to illustrate theoperation ofthe draw-stops upon the keyaction lever-bars and theoperation of the keys upon the key-levers in the different positions ofthe draw-stops and leverbars. Fig. 10 is organ, and a the key-deskthereof.

a fragmentary perspective detail, partly sectional, of a part of thekeyaction, designed to illustrate the connection of a key and stickerwith individual key-levers of different sets and the consequentconnection throughtrackers of ditterent sets of said key with thepallets controlling the throats of ditferent pipes. Fig. 11 is afragmentary perspective detail, partly sectional, of a part of thekey-action, designed to illustrate the connection of individual trackersand of the pallets which said trackers control, with two keys an octaveapart upon the board. Fig. 12 is afragmentary side sectional elevationaldetail, retn'esenting parts of the key and drawstop actions in thepositions which they occupy when given stops are drawn. the key-actionlever-bars.

Similar letters of reference indicate Corie spondiug parts in all thefigures.

In the drawings, A represents the caseof the The case is preferablyconstructed in imitation of the appearance of the cases ofuprightpianos.

P are the pipes, superimposed in a vertical position upon thewind-chest, and together occupying the full height, breadth, and depthof the rear portion of the casing. Any suitable number ofstops ofpipesmay be employed. In the organ represented two stops are supposed.

(l is the wind-chest, which occupies a horizontal posit-ion near thelower portion of the case.

I) are the bellows feeders, which supply wind to the wind-chest, two ofwhich are employed and respectively connected to the two pedals E E. Thefeeders, as will be understood by reference to Fig. 1, are applieddirectly to and form the bottom of the windchest, so that under theoperation of the pedals they feed direct and withoutintermediatereservoir into the wind-chest.

In stating that the feeders form the bottom of the wind-chest we mean tobe understood as saying that the fixed boards of the feeders form thebottom board of the wind-chest; or, conversely stated, that the bottomboard of the wind-chest forms the fixed boards of the feeders, whichlatter in consequence must of course communicate direct with the wind-Fig. 13 is a top plan view ofone of.

chest through suitable valve connections. The connection of each movableboard of the feeders with its pedal is by means of a strap or kindredflexible connection, d,which passes over a pulley, (I and through theintervention of which the depression of a treadle oocasions the lift ofthe movable board of and the consequent compression of its feeder, whilethe gravitative return of the movable board of said feeder after itscompression oecasions the elevation or return of the connected pedalinto position for action.

F is the bellows-reservoir, which we apply in a vertical position to therear of the keyaction, and preferably at one end of the case, as shownin Figs. 2 and 3. This reservoir has communication, through the openingf, with the wind-chest. The placing of the reservoir in a verticalposition to the rear of the key-board action and to the side or end, oreven back of, rather than beneath, the windchest, enables us to placethe wind-chest so low down in the case as to atford the necessary heightwithin the case for even the longest pipes.

The fact of placing the reservoir in the manner described, rather thanbeneath the windchest, of course prevents said reservoir from acting asan equalizer between the windchest and the bellows-feeders. This,however, is attended with no disadvantage in the operation of the organ;but, on the contrary, is attended with the great advantage of enablingus, as stated, to employ longer pipes than could otherwise be appliedwithin a case of'a given height, and, more than this,to obtain thedecided advantage of having the windforced, under the pressure of thebellows-feeders, direct into the wind-chest, and thence of course directto pipes, rather than of having it enter the wind-chest under simply theexpansive force of the reservoir itself, which is not so great as thedirect-acting forceot' the feeders. the reservoir, it being understood,receiving only the surplus wind from the wind-chest.

c c c" c are the pallet-levers, equipped with the pallets which controlthe throats of the pipes. These pallet-levers are levers of the firstorder and are contained within the windc-hes't.

G are the keys of the key-board, the same being levers of the secondorder fulcrumed at g, and mounted in the key-desk. Each key rests upon avertical sticker, H, suitably supported in the case, suitably guided forvertical movement under the depression of its key, and resting as to itslower extremity upon a sticker-spring, h,which, after the depression ofa key and sticker, operates to elevate or return them to their normalposition.

1 1 l" I are the key-action levers, termed herein the key-levers, ahorizontal series of which, corresponding in number with the number ofthe key s, constitutes a set of k y-levers,a predetermined series,correspond ing withthe number of draw-stops, of which sets is employed.In the organ represented,

tnake no further reference either to it or to the said key-levers, whichare a component part thereof.

Each key-lever is a lever of the first order, and has its fulcrummidwayof its length-upon a given key-action lever-bar, termed herein alever-bar, and all the key-levers of each set have their fnlcra upon anindependent lever-bar, the four of which bars employed are respectivelydesignated K K K K Of course the number of lever-bars must correspondwith the number of sets of key-levers, and must be lessened ormultiplied therewith. The lever-bars, one of which is shown in plan inFig. 13, are hinged conveniently, by means of pivot-ears lc at theirextremities, to suitable supports in the case, and each lever-bar isprovided with an arm, k", extending rearwardly and away from the pivotsof the bar, so as to afford a point of leverage, force applied to whichwill occasion a slight up and-down movement of said leverbar about itspivots, so that each bar is practically vertically adjustable. Theadjnstment that is to say the lift or drop of the respectivelever-barsis etl'ectuated by the employment of draw-stops L L L L, ofthe following construction: Each draw-stop, and reference is nowparticularly directed to Figs. 4 and 5, is conveniently composed of ahead and of a cylindriform rod or body, I, fitted to slide in suitablebearings or ways, a formed in the keyslip or other member of the case.The rod of each draw-stop is formed with an inclined plane, 1*, upon thesurface of which rests and travels the toem of a draw-stop lever, M,which latter is conveniently made by bending a piece of wire, after themanner shown in Figs. 4 and 5, to form it into a bellcrank lever, havingits fulcrum at m in the key-slip, and the rearwardly-projecting arm ofwhich is prolonged to an extent necessary to cause it to overhang thearm of one'of the lever-bars, to which bar the said lever is linked orconnected by means of a stop-action wire, N.

In the organ represented the four central draw-stops are connected, asshown in Fig. 2, with the four lever-bars, a separate stop-action wire,respectively marked N N N N, being the link between the respectivedrawstop levers and the respective key-lever bars. First assume aparticular draw-stop at rest, or

-in the position represented in Fig. 6; then it is obvious that whensuch drawstop has been drawn out into the position represented in Figs.8 or 9 the toe of its draw-stop lever will have been caused to travel upthe inclined plane upon its rod, and the lever itself will have beendeflected, so as, through the instrumentality of its stop-action wire,to have occasioned, as shown in the said figures, the elevation of theparticular lever-bar with which said wire is connecteda movement ofcourse resultingin the elevation or, more properly,tilting to apredetermined common inclination of the entire set of keylcvers withwhich said lever-bar is provided. A subse quent return or pushing in ofthe draw-stop, permitting the descent of the toe of the d rawstop leverupon the incline, will likewise, therefore, occasion the drop of thesaid leverbar and its set of key-levers to their normal position, orthat represented in Figs. 4 and c.

it is proper to note here that the lateral or two end drawstops whichappear in Fig. 2 of the drawings are respectively connected with theoctave-coupler and with the forte, and therefore do not require furthermention herein.

It will now be understood that by the movement of the four centraldraw-stops,wl1ich are those connected with the four key-actionleverbars, any one, any two, any three, or all of said lever-bars may belifted, so as to occasion the common upward tilt of the set or sets ofkey-levers which said bar or bars respectively carry, and which tilt isfor a purpose now to be explained.

All of the key action levers composing a given set are parallel witheach other, but the levers of adjacent sets (adjacent when considered asto vertical disposition) occupy different relative angular positionsthatis, for instance, to say,the key-levers I, which compose the upper setare, as represented in Fig. 3, all disposed at a given common angularinclination-tor example, that shownwhile all of the key levers l of. theset of levers imme diately beneath the upper set are disposed at adifferent common angular inclination, or at an inclination which is, forinstance, almost right'augular to the inclination ot the upper set; andagain,in like manner,the levers l 01' the third set while parallel withthe levers I of the upper set are almost right angular in inclination tothe lovers 1 of the second set, as well as to the levers 1 of the fourthor lower set, which latter are parallel with the levers l of the secondset. Each sticker is connected with one key-lever of each set, so thatall of the key-levers of each set are connected, through the medium ofthe stickers, with all of the keys in the key-board; or, to put it inother words, a given key-lever in each particular setof key-levers isconnected with a given key in the keyboard. It is manifest, therefore,that when aparticular key is depressed the particular key-lever of eachset of keylevers with which the sticker of said key is connected will becaused to move about its l l l t l l l i fulcrum; or, in other words,that the depres sion ota given key will necessarily occasion thesimultaneous tilting of four of the keylevers in the four sets ofkey-levers, and this, whether the lever-bars which respcctivelycarrysaid four key-levers bein their normal posi tion or lit'ted, one ormore, about their pivots by the action of the draw-stops which controlthem. as will be understood by a reference to Fig. 12.

The connection between the inner ends of the key-levers and the treeextremities of the pallet-levers of the wind-chest is by means ofvertical iods known as trackers or tracker-wires OO O" O", which wearrange in an organ having two stops of pipes, in the following manner:Two sets of trackers which, in the mountingot'thc organ, lierespectively in two separate but parallel longitudinal vertical planes,are employed, and each tracker of each set of trackers, excepting, asshown in Fig. 3, the twelve end trackers ot' the outside eud of each set'of trackers, is, as shown in Fig. ll, by being passed through the innerends of respectively connected with two keylevers belonging to twoadjacent sets of keylevers, so that each tracker, except the fortyeightend trnckers,as above stated, is, by rca son ot'the divergent angularinclination of the key-levers of adjacent sets, connected with two keysan octavo apart upon the board. Now, the key G shown in Fig. 1.0 iscounecl'ed by its sticker H with the four independent key-levers I l ll, which are each respectively members of one of the four sets ofkey-levers. \Vhen, therefore, the said key is depressed,soas to depressits sticker, each one of the abovenamed key-levers is tilted about itsfulcrum. The keylevcrs I and l, which, considered with reference totheir attachment to the sticker, occupy divergent angular positions,arelongcr than the levers l and i and, as shown, respectively connectedat their rear ends with the trackers O O which belong to one set oftrackers, while the shorter key-leversl" and l are similarly connectedwith the trackers O" and O" which belong to the other set of trackersi"he trackers O U are at their lower extremities respectively connectedwith the palletlcvers c c, which respectively control two pipes, l P, anoctave apart in the same stop of pipes. The trackers 0 and 0 are in likemanner at their lower extremities connected with the pallet-levers c"and c, which respectively control two pipes, P P", an octave apart in adifferent stop of pipes. It will be obvious, therel'ore, that since adepression of the key in question will occasion the tilting of allt'ourot'the connected key-levers, that then ifsuch tilting shalloccasion the elevation of all four trackers, all four of the pipesdesignated in the twoslops will becanscd to speak, and in such mannerasingle key will be caused to perform a quadruple duty in causing tourseparate pipes of separate stops to speak simultaneously. It is,moreover, to be nndcrstood that each one of the trackers of the two IOCsets of trackers which is connected with two key-levers (and we now omitreference to the twelve outside trackers of each set of trackers, which,as stated, are in communication with but a single key-lever) is, throughsaid two levers and by reason of the divergent inclination,

, considered with reference to their attachment set of the parts-that isto say,rwhen the leverbars K K are in their normal position and notliftedare sufficiently above the upper surface of the inner end of thesaid keylevers I I to permit the depression of the key G or the key G,with which the keylevers I and I are respectively connected,

and the consequent deflection or tilting of said key-levers to bewithout influence upon the said tracker O and its said pallet-lever c.In like manner the tracker O", which in said Fig. 11 is shown connectedwith the pallet-lever 0 passes through holes in the inner ends of thekey-levers I and 1 which are respectively connected with the keys G andG, and issimilarly provided with buttons B and B", which arerespectively applied in such mannerthatin the normal set of theleverbars K" and K a depression of either the key G or G will occasionatilt of said key-levers I and I, which tilt will yet be withoutinfluence upon the tracker O" and its'pallet-lever c. It will be finallyunderstood. therefore, that either the key G or the key G, which, asalready stated, are an octave apart upon the board, can be made tocontrol either the pallet-levereorthe pallet-lever c", and so cause apipe in adifl'erent stop to speak.

In the entire foregoing explanation we have assumed each of thekey-action lcverbars to be in its normal position or down, and all ofthe draw-stops which control said leverbars to be in; and inthis'assumed pos'tion of parts, as stated it is clear that thedepression of the keys will be withoutiutluence upon the pipes, the setof the buttons upon the trackers being such that the deflection ortiltofthekey-levers occasioned by the depression of the keys is insufficientto occasion any or such an encounter between the inner ends of thekeylevers and the said buttons as to cause the lift ofthe trackers andthe opening of the pallets ot the pipes. It will therefore be obviousthat in order to cause the keys to operate upon the pallets of the pipesit is essential that one or more of the draw-stops should be pulled outand one or more of the key-action levenbars be thereby lifted, so as toimpart a sufficient primal inclination toa given set or sets ofkeylevers to occasion the encounter of the inner .the principle of ourinvention.

end-ofa given lever of such set with the button of a given tracker, andthe consequent lifting of the tracker and pallet upon the depression ofagiven key. This action of controllingthe set of the lever-bars will bebetter understood by a reference to Figs. 6, 7, 8, and 9.

In Fig. 6 the draw-stop L represented is in, and the lever-bar Kconnected therewith in its normal position. It is obvious that in thisposition a depression of the key G will simply occasion the tilting ofthe key-lever I from the position which itisshown as occupying in saidFig. 6 to that which it is shown as occupying in Fig. 7, and that thistilting will of course be without effect upon the pallet-lever c, thebutt-on B of the tracker Oof which is not in range of said key-lever.

In Fig. 8'the draw-stop L is shown drawn out, and the lever-bar K shownin the position into which it is lifted by such drawing out of thedraw-stop. be noticed that thebutton B of the tracker O is against therear end of the key-lever I, so

that when the key G is depressed, as shown in Fig. 9, so as to tilt thekey-lever, the latter lifts the button and tracker O and occasions thedeflection of the pallet-lever c and the consequentspeaking of the pipewhich said pallet controls. 1

Having now described a good construction of an organ embodying ourimprovements. it will be easily understood that the capability of anyparticular key for causing any particular pipe or pipes to speak isdependentin the first instance upon the cont-r01 by the draw-stops ofthe position of predetermined key-action lever-bats, and that accordingas one, two, three, or all of these lever-bars is or are lifted is theconnection of the key in question with a given pipe or pipes efl'ected.It will be also obvious that by the predetermined drawing of particularstops a given key can be caused either to sound alone a given pipe orsimultaneously to sound two pipes an oc tave apart either in the sameorin different stops of pipes, or simultaneously to sound three, four, or,according to the number of stops, agreater number of pipes, each in adifferent stop, or by twos, an octave apart in dilferent stopsresultsnever heretofore capable of accomplishment in a pipe-organ.

It will be clearly manifest that there are certain modifications andmechanical changes which can be made without departing from Thus, forinstance, it would be quite possible to arrange the key-actionlever-bars so that instead of moving in a slight are about a radialpivot they should move vertically up and down; thus. also, other formsof draw-stops might be employed to efi'ectuate the lift and drop of saidlever-bars; thus, again, the precise construction of the wind-chest andthe application of the pipes and pallets thereto might be modified. Itis also to be understood that any predetermined number of pipes whichthe case of the organ is capableof containing In this position it willmay be applied. If desired, two bellowsreservoirs may be applied, one ateach end of the case; or the reservoir might be placed along the back ofthe case, although this would not be a convenient arrangement. Thefeeders may also, if desired, be driven by hand or by other motive powerthan pedals.

We have also described an organ containing four sets or banks ofkey-action levers employed in connection with two stops of pipes. lVe donot, however, restrict ourselves to four sets of these key-levers, 'asmore or even less than four may be employed, and more than two stops ofpipes. Itwould also be possible to modify the character of the variouslevers, as such, employed, both as to the keys proper and as topallet-levers; or, in fact, to adopt all such small workshop expedientsof construction and arrangement of minor parts as are common in pianoand organ manufacture. The gist of the construction, however, so far asthe key-action is concerned, resides in the crossing of thekey-levers,or, more properly, the angling apart of the key-levers of differ entsets from a common sticker and key, so that a single key is caused tocontrol pipes of either the same or of different stops an octave apart,from which construction as embodied by us is obtained in the mostcompact form an organ of great variety and disproportionate power oftone.

Having thus described our invention, we claim and desire to secure byLetters Iatcnt- 1. In combination with the wind-chest of a pipe-organ,bellows-feeders applied directly to and forming the bottom of saidwind-chest, substantially as and for the purposes set forth.
